How to Make Low Carb Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray to ensure your casserole won’t stick.
Step 2: Cook the Vegetables
Heat the olive oil in a large skillet over medium heat.
Add the diced onions and bell peppers.
Cook for about 5-6 minutes until they begin to soften.
Add the minced garlic and cook for another 30 seconds until fragrant.
Step 3: Brown the Ground Beef
Add the ground beef to the skillet with the vegetables.
Season with salt and pepper to taste.
Cook while breaking up the meat with a spatula until completely browned, about 7-8 minutes.
Step 4: Add Worcestershire Sauce
Stir in the Worcestershire sauce.
This will coat the meat mixture and enhance its flavors.
Step 5: Mix in Cream Cheese
Reduce heat to low.
Add the softened cream cheese to the skillet.
Stir until it melts completely.
This should coat the meat and vegetable mixture evenly, creating a creamy texture.
Step 6: Transfer to Baking Dish
Once fully combined, transfer the mixture to your prepared baking dish. Spread it out evenly.
Step 7: Layer Cheese on Top
Layer sliced provolone cheese over the beef mixture. Then sprinkle shredded mozzarella cheese evenly on top.
Step 8: Bake Until Bubbly
Place in your preheated oven. Bake for 20-25 minutes until the cheese is melted, bubbly, and slightly golden on top.
Step 9: Let It Rest Before Serving
Allow the casserole to rest for about 5 minutes before serving. This helps meld flavors together and makes serving easier.
